Abstract
The present disclosure provides a pixel driving circuit, a driving method, a pixel unit, and a display apparatus. The pixel driving circuit includes a driving transistor, a charging/discharging circuitry, a light-emitting control circuitry, a data write-in control circuitry, and a charging/discharging control circuitry, where a first electrode of the charging/discharging circuitry is connected to a second electrode of the driving transistor, and the charging/discharging control circuitry is configured to enable a first electrode of the driving transistor to be electrically connected to a second level output terminal under the control of a data line, and enable a second terminal of the charging/discharging circuitry to be electrically connected to a gate electrode of the driving transistor under the control of a first scan line.
